This Supplement is available from the National Technical Information Service (NTIS), Springfield, Virginia 22151 for $4.00. For copies mailed to addresses outside the United States, add $2.50 per copy for handling and postage. INTRODUCTION

This Supplement to Aerospace Medicine and Biology (NASA SP-7011) lists 238reports, articles and other documents announced duringDecemberil974inScientificand Technical Aerospace Reports (STAR) or in International Aerospace A.bsracts l.,4A . The first issue of the bibliography was published in July 1964; since that time, monthly supplements have been issued. In its subject coverage, Aerospace Medicine and Biology concentrates on the biological, physiological, psychological, and environmental effects to which man is subjected during and following simulated or actual flight in the earth's atmosphere or in interplanetary space. References describing similar effects of biological organisms of lower order are also included. Such related topics as sanitary problems, pharmacology, toxicology, safety and survival, life support systems, exobiology, and personnel factors receive appropriate attention. In general, emphasis is placed on applied research, but references to fundamental studies and theoretical principles related to experimental development also qualify for inclusion. Each entry in the bibliography consists of a bibliographic citation accompanied in most cases by an abstract. The listing of the entries is arranged in two major sections: IA.A Entries and STAR Entries. in that order. The citations, and abstracts when available, are reproduced exactly as they appeared originally in IAA or STAR. including the original accession numbers from the respective announcement journals. This procedure, which saves time and money, accounts for the slight variation in citation appearances. Two indexes-subject and personal author-are included. An annual index will be prepared at the end of the calendar year covering all documents listed in the 1974 Supplements.

Study of the effect of weightlessness on the functioning of the vestibular apparatus of the inner ear. It is shown that the absence of gravity, especially in combination with other accelerations, can lead to a number of vegetative and psychic disturbances in astronauts, since the organ of balance of the inner ear requires the presence of gravity as a stimulus to its proper functioning. In particular, the so-called 'space' sickness can occur. A.B.K.

The basic features of a new control concept are discussed, which may be used for synthesizing artificial specifically anthropomorphic biped walk. Reduction in system dimensionality is achieved by breaking down the control hierarchy into a nominal dynamics level and a level of perturbed modes. For demonstration the concept is applied to the synthesis of an active'exoskeleton-type biped walking robot. V.P.

The statistical interrelations between the deviations of the actual mean oblast rice harvest from the sliding mean harvest and the magnitudes of the meteorological elements are analyzed. It is found that the weather conditions in September have a decisive effect on the magnitude of the given deviations. Author

A Fuson Power Plant Aug. 1974 p 432-457 refs (For availability see N74-35146 24-25) The major systems of the Princeton Reference Design Fusion Reactor are reviewed from the point of view of identifying the hazards associated with normal and abnormal operation. Engineered safeguards and operational procedures are identified for eliminating the hazards or minimizing their consequences. The most serious credible accident is identified as the design basis accident and the design requirements specified for assuring that the consequences of that accident will not exceed the regulatory limits for accident conditions. Data are provided to show the maximum allowable levels of radiation and radioactive materials for normal reactor operation. It is concluded that the fusion power plant can be operated without any significant hazards to the public or plant personnel during normal operation. For most modes of abnormal operation, hazards to the public are not significant if the recommended safety procedures are instituted. Author
